Zusammenfassung:	The invention relates to novel, fine-pored PMMA foams and to the production of same. Formulations are used in production which comprise nucleating agents alongside suitable blowing agents. Unexpectedly, a stable, simple-to-produce PMMA foam with very fine pores and very good properties may be obtained according to the invention. La présente invention concerne de nouvelles mousses de PMMA, à pores fins, ainsi que leur fabrication. La fabrication de ces mousses comprend l'utilisation de formules qui, outre des agents gonflants appropriés, contiennent des agents de nucléation. De manière inattendue, il a été constaté que l'invention permettait d'obtenir une mousse de PMMA stable et facile à fabriquer, présentant des pores très fins et de très bonnes propriétés,
